First off, I am new to 3D printers. I purchased a FlyingBear P902. It was fun putting this kit together but I am now having issues getting it to work. Using the latest Repetier host and it connects but won't communicate with the printer. I have checked all wiring and it is correct. I have checked Baud rate in Windows 7 and in Repetier, both are set on the same value of 115200. Any suggestions ? I have tried earlier versions of Repetier with the same results.
